CVE-2026-33176
|
| Summary | Rails Active Support has a possible DoS vulnerability in its number helpers ### Impact Active Support number helpers accept strings containing scientific notation (e.g. `1e10000`), which when converted to a string could be expanded into extremely large decimal representations. This can cause excessive memory allocation and CPU consumption when the expanded number is formatted, possibly resulting in a DoS vulnerability. ### Releases The fixed releases are available at the normal locations. ### Credit This issue was responsibly reported by Hackerone researcher [manun](https://hackerone.com/manun). |
